CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 397,253, dated February5, 1889.

Application filed October 30, 1888, Serial No. 289,521. (No model.)

To aZZ whom it may concern:

Be it known that I, ELIJAH H. SPENCER, a citizen of the United States,residing at Yinona, in the county of Montgomery and State ofMississippi, have invented certain new and useful Improvements inCultivators; and I do declare the following to be a full, clear, andexact description of the invention, such as will I enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to theletters and figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a lop or plan view of a cultivator embodying myinvention.Fig. 2 is afront elevation of the same. Figs. 3, 4, and 5 are detailviews of one side beam of the frame.

The objects of my invention are to provide a cultivator-frame that maybeadjustable in width at its front end as well as in the rear of the same;also, to combine a series of plows, shovels, or other cultivatorimplements of gradually-increased size from the front to the rear of thecultivator-frame.

My improved cultivator consists of a frame, A, provided with handles B,a hook or clevis, plows D, and a front wheel, E,

The frame A consists of two side beams, 1 l, a central beam, 2, andadjustable rear bars, 3 3. Side beams,1 1, are usually constructed ofhard wood and shod with iron straps or plates l a 4 A row of holes, 5 5,are run through said side beams, 1, for the insertion of the plow orcultivator standards 0. Said standards are screw-threaded from their topend of the cultivator-beams l l and the central beam, 2, are perforated,as at in dotted line in Figs. 1 and 3 and at 10 in full line in Figs. 4:and 5, to receive a bolt, 11, screwthreaded its entire length andprovided with adjusting and lock nuts 12 13, so that the front end ofthe cultivator may be widened or narrowed, as shown by dotted lines inFig. 1.. The rear end of the cultivator may also be adjusted in width,as shown in dotted lines in Fig. 1.

It will be observed thatI construct my cultivator-plows in a novelmanner. The first or front pair of plows, 1414:, are small plows, thenext pair, 15 15, are larger, and each succeeding pair are of largersize. The object of this is to throw the earth more evenly against the.rows of plants than has hitherto been done. At the front end of thecultivator I provide a wheel, E, which is supported on a hanger, 17,secured to the central beam, 2, of the frame. Said wheel E serves for apivotal bearing when turning the cultivator at the end of a row.

I do not claim, broadly, an adjustable cultivator-frame; but what I wishto secure by Letters Patent is 1, In a cultivator-frame provided withside beams,1 1, and central draft-beam, 2, the combination of frontwheel, E, adjustable slotted rear comiecting-bars, 3, and a series ofplows or cultivator-teeth properly secured in said side beams and ofgradnally-increased size from the front ends to the rear of said beams,

? all as herein shown and described.

2. A cultivator provided with a series of plows or cultivatomteeth ofgradually-increased size from the front to the rear of the same, asherein shown and set forth.

In testimony whereof I affix my signature in presence of two witnesses.
